Warning strike started at Lufthansa: hundreds of flight cancellations. At Frankfurt/Main, 80 to 90 percent of the approximately 600 planned take-offs and landings have been canceled.

The strike is scheduled to end on Thursday at 7:10 a.m. Operations should have completely returned to normal by Friday. If flights within Germany are canceled, customers can use their flight ticket to take the train. Under no circumstances should passengers of canceled flights come to the airport, warned the airline.
